CONDENSJER PLATE SYSTEM.

Application filed April 28, 1924. Serial No. 709,395.

Jersey, have invented a new and useful Improvement in Condenser Plate Systems, of which the following is a specification.

In the use of the variable condenser of the type to which our invention relates, unexpected and oftentimes unaccounted for capacity losses have developed. These we believe are due to the imperfector incomplete contacts between the several plates of the stator or of the rotor, whereby imperfect metallic connection exists. To overcome this difficulty, we have designed a form of plate system wherein the several plates of the system are integrally connected at convenient points, so as to form a continuous strip of sheet metal folded back and forth from one end of the system to the other. It is, therefore the object of our invention to provide a plate system for variable con densers wherein capacity losses due to imperfect or incomplete metallic connection between the several plates are obviated, and maximum capacities for a given number of plates obtained.

In carrying out our invention, we make use of the structures and methods of construction as set forth in the following specification, taken in connection with the accompanying drawing, wherein Fig. 1 is a plan of a condenser frame with one form of our improved plate system mounted therein.

Fig. 2 is a plan of a set of stator plates of a slightly different form.

Fig. 3 is a plan of a strip of sheet metal with the stator plates laid out thereon, showing the form of connection as shown in Fig. 1.

Fig. 4 is a similar plan, but with the plates laid out to form the system as shown in Fig. 2.

Similar reference numerals refer to like parts throughout the specification and drawing.

In Fig. 1, we have shown a form of condenser frame, made up of the end plates 1, 2, connected by the three bolts 3, 4, 5, with the stator plate system 6 mounted thereon in the usual or any preferred .manner. As shown, the plates are spaced apart by spacing'washers 6, with the elongated washers 7, 8, spacing the outer stator plates from the end plates 1, 2.

The individual plates 9, as shown in Fig. 3, are substantially semicircular in form, with a notch 10 formed in the arcuate edge, and the two notches 11, 11 upon the dian'ietrical edge, which take over the three frame bolts 3, 4, 5. From an inspection of Fig. 3, it will be seen that pairs of the plates form a complete circle, with a diametrical strip 12 cut from the center with thenotches 11, 11 cut out at the same time. A central circular notch 13 is also cut out to provide for the rotor shaft (not shown). The pair of plates 9 are connected at the circumference by the two tangs 14, 14, and each of these plates is connected to the next plates 9, 9 by the tangs 15, 15, and so on throughout the entire strip. The strip of plates so connected is then folded across the tangs 14, 14, and 15, 15, back and forth to form the stator plate system, as shown at 6 in Fig. 1, so as to make a continuous metallic connection. It is then assembled in the condenser frame in the usual manner, with the spacing washers 6 inserted and maintaining the individual plates in rigid parallelism.

It has not been deemed necessary to show the rotor in connection with the stator mechanism, since the general construction of the condenser is well known and understood.

We are able to accomplish the same results as above described by the structure illustrated in Figs. 2 and 4. In this case the blanking lay out shown in Fig. 4 makes use of the individual plates 16, 16, 17, 17, of substantially the same form and shape as above described. The semicircular plates have their straight edges ranged parallel with the edges of the metal strip 18, and staggered as shown to economize material. The connecting tangs 19, 20, are immediately adjacent the straight edges of the plates, and are of about double the width of those shown in Fig. 3. When folded on the dotted lines, the plate system appears in edge View as shown in Fig. 2, and is assembled in the condenser frame in the same manner as above described in connection with the form shown in Fig. 1.

In stamping or punching the plate system from the strip of sheet metal in either of the forms shown, it is understood that the strip will be of a length to include an entire set of plates for a single condenser; that is to say, if it is to be what is known as an ll-plate condenser, the stator Willhave I six plates, connected as shown; likew1se, a 3-plate condenser will have twenty-two plates in the stator.

The location of the connecting tangs be tween the adjacent plates at their circumferences, as shownin each of the forms leaves the straight sides of the plates free for the proper interleaving of the rotor plates be tween them in the usual way, and at the same time makes the stator plate system of continuous metal from end to end, thereby obviating the capacity losses which are pres cut when the plates are separate, and connectedup by the contact of metal to metal.

We have confined our description and drawing to plates of substantially semicircular shape; but we wish it understood that the improvement is applicable to plates of different shape or contour, and would be embodied in any shape of plate so long as the individual plates are integrally connected together so as to form a substantially continuous strip of metal; and we intend that the appended claims shall be so construed.
